IMPROVEMENT IN REFLECTORS FOR RAILWAY-CARS.

Specification forming part of Letters Patent No. 151,082; dated May 19,1874; application filed September 29, 1873.

To all whom it may concern:

Be it known that I, GHAUNOEY S. BUCK, of St. Louis, St. Louis county,Missouri, have invented an Improvement in Lamp-Reflectors, of which thefollowing is a specification:

My invention consists in the arrangement, in a peculiarly-constructedrefleetor-case, of a series of flat metallic or silvered-glassreflecting plates or facets arranged around the curved back, said facetsbeing arranged or inclined so as to reflect the light from the lamplongitudinally and inclined downwardly in the car, (this reflector beingspecially adapted for railwaycars.) The top of the case has upon itsunder side a reflector to cast the light downward. The bottom of thecase is slotted to allow the introduction of the facets from beneath,the facets being held in by metallic tongues projecting across theslots. The facets are made removable, so as to allow the replacement ofany broken one without the disturbance of any other.

In the drawings, Figure 1 is a sectional perspective view.v Fig.2 is adetail bottom view,

partly in section.

The reflectorcase is formed of top and bottom parts A B, curved back 0,and flanged rim D, resting against the margin of a recess in the end ofthe car above the door, and the case is open in front. E E are flatsilveredglass or metallic reflecting plates or facets, narrowingupwardly, and held at the ends in slots a b in the top and bottom,respectively, of the reflectingcase, being held in place by the tonguesof metal b, bent transversely across the slots 6 of the bottom B. Theinner edge 0 of the slot 1) is flanged, to offer a firm hearing to theface of the facets E. Crossbars a serve to hold the upper ends of thefacets by their edges. The facets E are inclined inward at top, so as toreflect the light downwardly into the car, and, as the edges are inclose contact, they are made narrower toward the upper end for thispurpose. F is a reflectorplate, arranged in the top of thereflector-case to reflect the light downward. G is a lamp, of anysuitable construction, supported in the tray H. in the bottom of thecase. 6 is an opening in the top A, for the passage of the lamp-chimneyand escape of gases from the lamp.

The facets are so arranged in relation with the lamp that a ray of lightimpinging on the central line of each facet will be reflectedlongitudinally in the car, and, of course, rays falling to either sideof said lines will be reflected in different directions to each side ofsaid longitudinal planes of rays, so that the light is well diffused toall parts of the car froma reflector in each end, over the doors, andthe inconvenience and dirt resulting from the use of lamps within thecar either overhead or scattered along the sides, are avoided.

I claim as my invention- The reflector-case composed of top and bot tomplates A B, curved back 0, provided with the series of inclinedrefleetin g facets or plates E, rim D, and top reflector F, all arrangedsubstantially as and for the purpose set forth.
